As shown in Figure 1, in a kind of detection device for detecting molten metal mobility of the invention, the heated base
1, test disks 2, shunting disk 3a, 3b and sprue cup 4a, 4b are cylindrical, and heated base 1, shunts disk at test disks 2
3a, 3b and sprue cup 4a, 4b coaxial arrangement.It is examined using a kind of detection device for detecting molten metal mobility of the invention
When surveying the mobility of molten metal, after the molten metal in the detection slot 8 of test disks 2 solidifies, needs to obtain in detection slot 8 and coagulate
Solid molten metal length to evaluate the mobility of molten metal, so, the length of the molten metal solidified in needing to obtain detection slot 8
When spending, shunting disk 3a, the 3b for needing will test 2 upper surface of disk are removed, it is preferable that the upper surface of the test disks 2 with
The lower surface for shunting disk 3a, 3b is separably attached, as shown in figures 1 and 3, described as a kind of specific embodiment
Shunting disk 3a, 3b includes the first shunting disk and the second shunting disk stitched and fastened, and described sprue cup 4a, 4b include that split exists
The first half tundish 4a together and the second half tundish 4b, need that disk 3a, 3b will be shunted removed from detection plate when, first by the
Half tundish 4a and the second half tundish 4b disassembly, then the first shunting disk and the second shunting disk are dismantled and are removed again, thus
It can be observed that the length of the molten metal solidified in detection slot 8.For the ease of the split of the first tundish and the second tundish, such as scheme
Shown in 1 and Fig. 2, the first tundish is equipped with card rib 5a, and the second tundish is equipped with card slot 5b, the first half tundish 4a and the second half tundish
4b is fastened togather by card rib 5a and card slot 5b.
When detecting the mobility of molten metal using a kind of detection device for detecting molten metal mobility of the invention,
Molten metal is flowed into detection slot 8 from the inner cavity of tundish by liquid injection port 11, fluid guidance port 10 and inlet 9, in order to prevent metal
Liquid is overflowed from the opening at 8 top of detection slot, and the lower surface for shunting disk 3a, 3b is bonded with the upper surface of test disks 2, point
The lower surface of stream disk 3a, 3b will test the top opening closing of slot 8.In order to make detection slot 8 have enough length, to meet stream
The test of the dynamic preferable molten metal of property, as shown in figure 4, the detection slot 8 is spirally centered around around the center of test disks 2,
Spiral shape mosquito-repellent incense of distribution shape of the detection slot 8 in test disks 2 such as us usually, in this way, working as molten metal from feed liquor
After mouth 9 enters detection slot 8, molten metal is flowed along detection slot 8 to the end of detection slot 8 from the starting point of detection slot 8, this spiral
Property detection slot 8 longer detection slot 8 can be arranged in the lesser test disks 2 of size so that the ruler of entire detection device
It is very little compacter.After the molten metal solidification in detection slot 8, for the ease of obtaining the length of the molten metal solidified in detection slot 8,
The scale of 8 length of label detection slot can be set in test disks 2, at the starting point of detection slot 8, scale marker zero,
A scale is identified to its space from end unit length from the starting point of detection slot 8 along detection slot 8；Pass through quarter with can be convenient in this way
It spends to read the length of the molten metal of solidification.
Correspondingly with a kind of detection device for detecting molten metal mobility of the invention, the present invention also provides a kind of use
